I've been on Femcon for 5 months now and the only side effect I have is oversensitivity. I cry at the drop of a dime and it seems as if EVERYTHING hurts my dam feelings, lol. I have actually lost 10lbs (over a five month period) since taking this pill. I too like many other new users have never taken any type of birth control and I'm 31 years old. I guess it just depends on the individual. I HIGHLY recommend this pill...definitely for first time users. I love it!
